Network virtualization is the technology that allows the simultaneous operation of multiple logical networks (also known as overlays) on a single physical platform. Network virtualization permits distributed participants to create almost instantly their own network with application-specific naming; routing and resource management mechanisms such as server virtualization enables users to even use a whole computing center arbitrarily as their own personal computer. Recently, network virtualization has received significant attention since it is expected to be one of the major paradigms for the future Internet as suggesteded by numerous international initiatives on future networks, e.g. PlanetLab (USA, International), GENI (USA), AKARI (JAPAN), OneLab2 (Europe) and G-Lab (Germany).

Network virtualization is a rather new technology with performance aspects not yet eminent but expected to grow with its spreading application, the scaling of this new type of virtual networks, and the dynamics of invoking them. These new performance aspects may comprise the quality of isolation, fairness among virtual systems, location transparency of virtual services, quality of synthetic virtual resources, and scalability of the composition of virtual networks and services and of the management mechanisms for virtual networks and their communication patterns.

As a follow-up of the successful 20^th ITC Specialist Seminar on Network Virtualization (Hoi An, Vietnam, 20-21 May 2009), the objective of this special issue of the IJCNDS is to address techniques, architectures, performance models, and performance engineering methods leading to real world network virtualization solutions that provide users with efficient techniques for creating and operating their own high performance virtual network.

Subject Coverage
Topics of interest are amongst others, but not limited to:

• Performance issues of virtualization techniques on routers and end hosts
• Isolation and fairness among multiple virtual systems on a single host
• Performance issues of virtualized operating systems and server virtualization
• Performance metrics for virtualized hosts or routers
• Measurement techniques, e.g. for the parallel throughput on a single host
• Performance evaluation of virtualized packet switching technologies
• Middleware for virtualization

• Performance issues of bandwidth and resource virtualization techniques
• Media access mechanisms for virtualization in wireline and wireless environments
• Performance of multiqueue network interfaces
• Fairness among overlays using the same transmission system
• Scheduling mechanisms for virtualized connections
• Models for resource contention between virtual networks

• Performance issues of overlays for future network architectures
• Performance of overlay composition (including isolation and fairness)
• Performance of content/data-oriented routing
• Stability, robustness and resilience of overlays, virtual networks and self-organising mechanisms
• Static and time-dependent topology/resource/user models for overlays
• Metrics for adaptation and dynamics in overlays
• Mechanisms, capabilities and accuracy of network coordinate systems ( NCS )
• Traffic engineering for virtual networks
• QoS and quality-of-experience (QoE) in overlays
